FUEL-EGONOMIZER FOR INTERNAL-COMBUSTION ENGINES.

Patented July 2, 1918.

Application led June 7, 1916, Serial No. 102,307. Renewed April 3, 1918. Serial No. 226,530.

To all whom t may concern:

Be it known that I, OSCAR GLovER, a citizen of the United States, residing at Louisville, in the county of Jefferson and Staf/e of Kentucky, have invented certain new and useful Improvements in Fuel-Economizers for Internal-Combustion Engines, of which the following is a specification.

The device which is the subject-matter of the present application for patent is an attachment for motor vehicle engines of the internal-combustion type, and has for its object to reduce the amount of fuel consumed by the engine, and to obtain a maximum speed and power with a minimum quantity of fuel.

The invention also has for its object to provide a device which prevents or minimizes carbon deposits on the intake and exhaust valves of the engine.

A further object of the invention is to provide a novel and improved priming dev1ce.

The objects stated are attainedby means of a novel combination and arrangement of parts to .be hereinafter described and claimed, reference being had to the accompanying drawing in which- Figure 1 is a side elevation of the device applied to the engine; Fig. 2 is a vertical section of the device, and Fig, 3 is an elevation thereof.

Referring specifically to the drawing, 5 denotes the engine of an automobile or other motor vehicle, the engine being of the ordinary internal-combustion type and having an intake manifold `6 to which the carbureter 7 is connected. To the intake manifold, between the carbureter and the fuel inlet of the engine cylinders, is connected an auxiliary air supply comprising a pipe 8 connected to a chamber 9 which is cylindrical in shape and closed at its ends, one of the closures being a removable screw plug 10 which is hollow Jfor a purpose to be resently described. This chamber has a serles of Alongside the chamber 9 is mounted an oil reservoir 16, which may be anordinary oil cup having a delivery pipe 17 which is connected to the valve 13. The How of oil from the reservoir is controlled by a valve 18 having a stem 19 extending from the top of the reservoir, and on the lattery is mounted a support 20 for a valve operating lever 21 fulcrumed intermediate its ends to the support, as indicated at 22. One end of the lever is connected to the valve stem 19, and its other end is connected to an operating rod 23, the lever having an aperture through which the rod loosely passes. Above the lever, the rod carries an abutment 24, which latter may be a nut, provided with a lock nut 25, the rod being screw-threaded to receive the same. Thus, when the rod is drawn down, the lever is swung to open the valve 18. A. valve-closing spring 26 is also provided. 0n the lower end of the rod is an abutment 27, which latter may also be a nut screwed on the rod.

The valve 13 is a three-way valve having one side port and two end ports, the valve casing being so positioned that the end ports are in vertical alincment. The pipe 17 is connected to the top end port, and the pipe 8 is connected to the bottom end port, Whereas the side port communicates with the outlet of the chamber 9. The valve proper is a turning plug 13Et having ways corresponding to the valve casing ports. The valve plug has a crank arm 28 at 'one end on the outside of the casing to which is connected an operating rod 29 extending to a point within easy reach of the driver. On the other end of the plug is a fork 30 into the path of which the abutment 27 extends. The pipe 17 carrie.c a guide 31 for the rod 23.

The normal suction of the engine 5, while running, and the valve 13 being open, takes in air at the inlets 12, and in its passage to the intake manifold 6 the air is heated upon passing through the coil 15, The heated air entering the intake manifold mixes with the fuel charges, resulting: in the seme being highly vaporized, thereiajl f-fmring a saving of fuel, it having been found that the speed of the engine is increased without increasing the fuel supply.

Upon turning the plug 133 slightl so that the fork 30 strikes the abutment 2 the rod 23 is drawn down, thereby opening the oil valve 18, and upon restoring the plug to full open position, the forli is Withdrawn from the abutment, to allow the oil valve to close. The oil dropping down the pipe ILT enters the valve 13 and passes f-itrzlight through the way in the plug comnactiu the top and bottom ports to which the pipes il' and 8 are connected, said pipes being; here in vertical alinement. The air from the chamber 9 enters the valve through the eide Jort. Thus, it will be seen that the oil fire; s into the pathv of the current of air and is carri ed by the same into the intake immit'ohl G, and passes from the latter into the engine cylinders. The mixture of air and oil is heated in its passage through the coil 1T, and it enters the engine cylinders in the form of a finespray, which lubricates the intuire null exhaust valves, and prevents the eofmoulaa tion of carbon on the same and in ienis thereof, the carbon being discharged with the exhaust. Excessive heatingl ot the @flinders is also prevented.

The plug 10 is made hollow so tim it may serve as a reservoir to hold a supply of gasolene for primingthe The bottom of the plug is closed hg; :l was movable screw cap 32 having an outhf, loro the chamber 9, said outlet being provided with a valve 33 having an upstanding;` siem 34. In the top of the plug is an an vont port provided with a valve 35 havin en opstanding stem 36 projeetin from the #op of the plug and engageable y a fiat spring; 37 s'er'vinl to normally hold said val *e closed. T e valve 33 is also provided with a closing spring 38. From the bottino ef the valve 35 dependsa stem 39 hipwnrr a socket 40 at its lower end into wheil the up er end of the valve stem 34 loosely seats.

en it is desired to disohar e gesoione from the plug 10 into the cham er il, it necessary only to press down on the Stem Re? whereupon both valves open, the bottom valve 33 admitting gasolene into the chamber 9, and the top valve 35 admitting air into the plug 10. Upon releasing the valve stem 56, the valves are at once closed by their springs.

ln the chamber tl, below the plug 10, is a sponge 4l or some other absorbent material.

ln order to obtain a richer fuel mixture news.. ry when starting in cold Weather, gasolvne is let into the chamber 9 from the plug 10 by operating the valves thereof as hereinbefore descrl'ied. The gasolene drops on the .sponge 4l, and the air upon passing through tho latter vaporizes the gasolene :nul takes it to the intake manifold (i. The sponge also serves as a Screen to keep dust out of the cylinders.

The preferred embodiment of tlie invention has been .shown and described, but it witl be evident that various changes and nmditieations in the structural details may be made without departure from the spirit and scope of the invention as claimed hereiinftol'.

'l claim t The wunbination with an internal-co1^n liusion engine; of :i chamber having an air init-,t and tn outlet connected to the intake ol' Elu: Y, i o. a plug closing one end of the illumina Luid plug being hollow to serve as o ioei reservoir, the inner end of the plug having nu outlet port into the chamber, and its outer end having a vent port, and valves for; said ports.

2 The combination with an internal-Colm le stron engine; of a chamber having an air inlet and an outlet connected to the intake of the engine, a plug closing one end of the chamber. said plug being hollow to serve as a fuel reservoirtlie inner end of the plug lee ring: an outlet port into the chamber, and its outer oud having a vent port, valves for said ports, und an operative connection between 'the valves. i
